Sludge sedimentation
Depending on the size and density of particles, and physical properties of the solids, there are four types of sedimentation processes: Type 1 – Dilutes, non- flocculent, free-settling (every particle settles independently.) Type 2 – Dilute, flocculent (particles can flocculate as they settle). Type ... Visa mer Sedimentation is a physical water treatment process using gravity to remove suspended solids from water.

The particles which settle out from the suspension become the sediment, while in water treatment this is known as sludge. When this thick sediment continues to settle, this is called consolidation.
